Audiobus: Use your music apps together.

What is Audiobus?Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Audiobus is the app that makes the rest of your setup better.

iOs iSEM AU... Where'd the poly/mono go?!

So I just noticed that in iSEM, in AU mode, as there's no keyboard view, that there is no mono/poly button... Hmmm... I've poked everywhere... Where the F is Waldo?!!!


  • I have this same issue - I can only find it in stand-alone.

  • Inquiring minds want to know

  • There's no way to change the state in the AU, however, if you save a patch as mono or poly in the standalone version, it will retain that state in the AU.

    There are a few other issues with feature parity between standalone and AUv3 versions noted here.
